MIL-SHIPS-W-2181
Back in February 1958, under the heading of Project NS186-200, three pre-production samples of a new Bulova ‘submersible wristwatch’ were delivered into the charge of the US Navy’s Lieutenant Commander W F Searle in Building 214 in Washington Navy Yard. They were there to undergo trials of ‘watertightness, readability in darkness and various subjective tests…’ They’d be tested at 392ft in the lab and then on some working dives to be checked for watertightness, usability and legibility. This was the second trial of the new watch; the first had been in May 1957.
Two of the three failed; the watches had a tell-tale patch on the dial that would change colour if moisture entered the case and, although there was no sign of moisture and the watches ran happily, the patches changed.

With the lilt of Irish laughter
Every day and in every way
Now forever and ever after."
